LS weight savings

[CamaroAJ]

what about big bore LSx engines? wouldn't those have roughly the same power curve? the LS7 is already 427 so boring it to 454 would be in the same area. it would also be in a smaller package and have a lighter weight.

I'd assume you could do some really cool things with over boring to 454 and maybe even larger, however, I'm not aware of anyone boring a LSX to the 555ci I'm running.... Yes all motors have a shortfall somewhere, to much torque, not enough, come on to strong or doesn't come on enough at different RPM ranges..... The best you can do is try to match the drive train to your needs/desires and start tuning the chassis/drive-line from there...

The relevant point being however, you can produce some really trick combos (LSX, Small block or Big Block) that suit your ride and driving preferences.....
